Plato, if called upon for an answer to this reasoning, would probably have allowed it to be just; but would have said that the "diluted friendship" pervading all the Guardians was apt and sufficient for his purpose, as bringing the whole number most nearly into the condition of one organism. Strong exclusive affections, upon whatever founded, between individuals, he wishes to discourage: the hateful or unfriendly sentiments he is bent on rooting out. What he desires to see preponderant, in each Guardian, is a sense of duty to the public: subordinate to that, he approves moderate and kindly affections, embracing all the Guardians; towards the elders as fathers, towards those of the same age as brothers. Aristotle's expression--[Greek: phili/a u(darê/s]--describes such a sentiment fairly enough. See Republic, v. pp. 462-463. It must be conceded, however, that Plato's _language_ is open to Aristotle's objection.] [Side-note: Plato has strong feelings of right and wrong about sexual intercourse, but referring to different objects.] But we must recollect that it is these very sentiments which Plato impugns and declares to be inapplicable to his Guardians: so that an opponent who, not breaking off at once with the cry of horror uttered by the Indians to Darius, begins to discuss the question with him, is bound to forego objections and repugnances springing as corollaries from a basis avowedly denied. Plato has earnest feelings of right and wrong, in regard both to the functions of women and to the sexual intercourse: but his feelings dissent entirely from those of readers generally. That is right, in his opinion, which tends to keep up the excellence of the breed and the proper number of Guardians, as well as to ensure the exact and constant fulfilment of their mission: that is wrong, which tends to defeat or abridge such fulfilment, or to impair the breed, or to multiply the number beyond its proper limit. Of these ends the Rulers are the proper judges, not the individual person. All the Guardians are enjoined to leave the sexual power absolutely unexercised until the age of thirty for men, of twenty for women--and then only to exercise it under express sanction and authorisation, according as the Rulers may consider that children are needed to keep up the legitimate number.
